File:North Solar Pole Over Two Days in Sept. 2011 -Hinode XRT-.webm
In September of 2011, Hinode spent a number of hours watching the north solar pole to perform helioseismology observations. This movie provides a view of the Sun as it appears in x-rays, which are primarily emitted by the upper parts of the solar atmosphere, known as the corona. The bright spots, known as "active regions", sit above sunspots and are sites of particularly strong magnetic activity. About two days of data are shown here, during which numerous "micro-flares" and several C-class (relatively weak) flares are observed.

Hinode is a Japanese mission developed and launched by ISAS/JAXA, with NAOJ as domestic partner and NASA and STFC (UK) as international partners. It is operated by these agencies in co-operation with ESA and the NSC (Norway).
